Heel data only shows up in Expedition intermittently. 
System is set up with a B&G H3000 Motion into a Digital Yacht WLN30 mux and then a TP Link router. 
Heel data looks good in the raw data log:
$IIXDR,A,-0.0,D,HEEL*4E

But doesn't show up in Expedition or in the log file. Heel looks good on the B&G display.
Could this be a parsing issue? Any other ideas?

Thank you,
Keith
